[0002] When the power line or power equipment is shut down for maintenance, in order to prevent electric shock accidents caused by unexpected power supply, it is necessary to load the grounding wire on the power line to protect the personal safety of the workers, and unload the grounding wire after the work is completed.

[0003] In the prior art, the workers climb the electric pole or the electric tower by means of the climbing tool to the grounding wire loading or unloading position, use the lifting rope to lift the grounding wire to the side, and use the insulating operating rod to hang the hook of the grounding wire on the power line to complete the loading of the grounding wire, and the workers complete the loading or unloading of the grounding wire by climbing up and down. However, the above method takes a long time in actual operation, resulting in low work efficiency. Therefore, the prior art uses a grounding wire clamp to load or unload the grounding wire by means of a unmanned aerial vehicle. However, the grounding wire clamp relies on a large number of electrical components such as electric motors and electromagnets.

[0046] This invention provides a grounding wire loading and unloading device to solve the technical problem that, in the prior art, when loading or unloading grounding wires using a drone with a grounding wire clamp, the grounding wire clamp relies heavily on electrical components, resulting in low reliability of grounding wire loading and unloading.

[0047] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0048] For easier understanding, please refer to Figures 1 to 6 The present invention provides a grounding wire loading and unloading device, comprising a multi-rotor UAV 1, a remote control module, a positioning auxiliary module 2, and a wire clamp module 4;

[0049] A grounding wire 5 is soldered onto the clamp module 4;

[0050] The bottom of the multi-rotor drone 1 is equipped with a mounting rod 3;

[0051] The positioning assistance module 2 is located at the bottom of the multi-rotor UAV 1 and is used to collect flight image information and obtain the grounding wire loading and unloading position and transmit it to the remote control module.

[0052] The multi-rotor UAV 1 is used to respond to the loading and unloading signal sent by the remote control module. Based on the flight image information, it clamps the wire clamp module 4 onto the hanging pole 3 according to the force, and drives the grounding wire 5 to be loaded at the grounding wire loading and unloading position based on the force, or unloads the grounding wire 5 from the grounding wire loading and unloading position.

[0053] The loading / unloading signal is used to indicate whether to load or unload the grounding wire 5.

[0054] Flight image information refers to image information during the flight of a drone.

[0055] The grounding wire loading and unloading positions include the grounding wire loading position and the grounding wire unloading position. The grounding wire loading position refers to the position where the grounding wire 5 is mounted, and the grounding wire unloading position refers to the position where the grounding wire 5 is unloaded.

[0056] In this embodiment of the invention, a grounding wire 5 is welded onto the clamp module 4. The grounding wire 5 is made of copper and is the main device for grounding. A hanging rod 3 is provided at the bottom of the multi-rotor drone 1, and the clamp module 4 carrying the grounding wire 5 can be clamped onto the hanging rod 3. A positioning assistance module 2 is also installed at the bottom of the multi-rotor drone 1 to provide visual assistance for loading or unloading the grounding wire. When the multi-rotor drone 1 receives a loading / unloading signal sent by the remote control module, it collects flight image information through the positioning assistance module 2. If the loading / unloading type corresponding to the loading / unloading signal is the grounding wire loading type, the multi-rotor drone 1 first clamps the clamp module 4 onto the hanging rod 3 by applying force according to the flight image information, and then flies towards the power line carrying the clamp module 4 with the grounding wire 5. Once it is determined that the multi-rotor drone 1 has flown to the vicinity of the power line, the positioning assistance module 2... Block 2 determines the grounding wire loading position. At this time, the multi-rotor UAV 1 is directly above the grounding wire loading position and slowly descends. It also uses the force application method to load and clamp the clamp module 4 at the grounding wire loading position. If the loading and unloading signal corresponds to the grounding wire unloading type, the multi-rotor UAV 1 flies to the position above the clamp module 4 according to the flight image information, descends vertically, and directly clamps the clamp module 4 on the hanging pole 3 through the force application method, thereby unloading the grounding wire 5 from the grounding wire unloading position. At this time, the UAV can lift the grounding wire 5 away from the power line and return to the ground.

[0057] Optionally, the positioning assistance module 2 includes a laser emitter and a camera; the laser emitter is used to emit three-point lasers to locate the installation and removal position of the grounding wire on the power line, and transmits the installation and removal position of the grounding wire to the remote control module; the camera is used to collect flight image information and transmit the flight image information to the remote control module.

[0058] In this embodiment of the invention, the laser emitter positions itself by emitting three laser beams to the power line. When all three laser beams land on the power line, it is determined that the multi-rotor UAV 1 is on the same vertical plane as the power line and the clamp module 4, thereby further determining the grounding wire installation / removal position and transmitting it to the remote control module. The camera is used to collect flight image information and transmit it to the remote control module.

[0059] Please see Figures 3-6 As shown, the wire clamp module 4 includes a wire clamp housing 401, two sets of wire clamp components, and a fixing pin 403. A grounding wire lead-out point 402 is embedded on the first side of the wire clamp housing 401, and a grounding wire 5 is welded to the grounding wire lead-out point 402. A guide rail groove is provided inside the wire clamp housing 401, and the two sets of wire clamp components are symmetrically embedded in the guide rail groove facing away from each other. The fixing pin 403 is fixedly connected to the two sets of wire clamp components respectively and is embedded in the guide rail groove; the fixing pin 403 is used to cause the other set of wire clamp components to open and release when one set of wire clamp components is tightened under force.

[0060] In this embodiment of the invention, the wire clamp module 4 includes a wire clamp housing 401, two sets of wire clamp components, and a fixing pin 403. A grounding wire lead-out point 402 is embedded on the first side of the wire clamp housing 401, for welding the grounding wire 5. A guide rail groove is provided inside the wire clamp housing 401, and the two sets of wire clamp components are symmetrically embedded in the guide rail groove in a vertical arrangement. The fixing pin 403 is embedded in the guide rail groove and is fixedly connected to the two sets of wire clamp components. When one set of wire clamp components is tightened under pressure and in a clamping state, the other set of wire clamp components opens and is in a non-clamping state through the linkage of the fixing pin 403.

[0061] Optionally, the wire clamp component includes two sets of clamping assemblies, a connecting rod shaft 404, and a button; the two sets of clamping assemblies are distributed facing each other and are movably connected to the connecting rod shaft 404; the connecting rod shaft 404 is embedded in the guide rail groove and fixed to the first side and the second side of the wire clamp housing 401; the button is integrally fixedly connected to the connecting rod shaft 404, and the button is used to trigger the corresponding two sets of clamping assemblies to rotate facing each other to tighten the clamping or rotate in opposite directions to open the clamping when the connecting rod shaft 404 is vertically displaced by force; the buttons of the two sets of wire clamp components are respectively fixedly connected to the fixing pins 403.

[0062] The clamping assembly includes multiple clamping parts and a jaw shaft 405. All clamping parts are fixedly inserted through the jaw shaft 405 and the connecting rod shaft 404 at intervals. The jaw shaft 405 is fixedly embedded in the first and second sides. Each clamping part includes a jaw 406 and a force-applying rod 407. One end of the jaw 406 is hinged to one end of the force-applying rod 407. One end of the jaw 406 has a jaw hole for fixedly inserting into the jaw shaft 405; the inner side of the other end of the jaw 406 is serrated. The other end of the force-applying rod 407 has a rod hole for fixedly inserting into the connecting rod shaft 404.

[0063] In this embodiment of the invention, the wire clamp module 4 includes two sets of wire clamp components. Each set of wire clamp components includes two sets of clamping assemblies, a connecting rod shaft 404, and a button. The two sets of clamping assemblies are distributed facing each other, and each set of clamping assemblies includes multiple clamping parts and a jaw shaft 405. The wire clamp module 4 is provided with four jaw shafts 405, which are distributed and fixedly embedded in the holes on the first and second sides. Multiple clamping parts are fixedly inserted through each jaw shaft 405 at intervals, and the clamping parts can rotate around the corresponding jaw shaft 405. The wire clamp module 4 is provided with two connecting rod shafts 404, which are embedded in the guide rail groove and fixed to the first side and the second side of the wire clamp housing 401. Each connecting rod shaft 404 connects the corresponding two sets of clamping assemblies in series. When subjected to force, the connecting rod shaft 404 can make vertical displacement movements in the guide rail groove, driving the clamping assembly to rotate around the corresponding jaw shaft 405 to achieve a clamping state and a non-clamping state.

[0064] It is understandable that the first and second sides of the wire clamp housing 401 are two opposing sides.

[0065] Each clamping assembly includes a jaw 406 and a force-applying rod 407. One end of the jaw 406 is hinged to one end of the force-applying rod 407. The hinged end of the jaw 406 also has a jaw hole for the jaw 406 to pass through and be fixed on the jaw shaft 405. The other end of the force-applying rod 407 has a rod hole for the force-applying rod 407 to pass through and be fixed on the connecting rod shaft 404. The inner side of the other end of the jaw 406 is serrated to increase friction.

[0066] The fixing pin 403 is embedded in the guide rail groove and is connected to the buttons of the two sets of wire clamp components to keep the relative positions of the two buttons fixed. This ensures that when the button of one set of wire clamp components is subjected to force and moves vertically downward, the button of the other set of wire clamp components also moves downward synchronously, causing the clamping parts of the other set of wire clamp components to open. Simultaneously, it ensures that when the button of the other set of wire clamp components is subjected to force and moves vertically upward, the button of one set of wire clamp components also moves upward synchronously, causing the clamping parts of that set of wire clamp components to open. The fixing pin 403 also serves as a limit, preventing excessive displacement of the two buttons and thus affecting the overall operation of the device. Each connecting rod shaft 404 is integrally connected to a button, and the relative positions of the two are fixed. When the button of the wire clamp component is subjected to force and moves vertically upward or downward, the corresponding connecting rod shaft 404 will move synchronously. The connecting rod shaft 404 pulls the other end of the associated force-applying rod 407 to move upward or downward. The force-applying rod 407 will rotate around the gripper shaft 405 as the center to tighten the clamp or rotate in the opposite direction to open and not clamp.

[0067] Optionally, the button can be set to a long, rectangular shape.

[0068] Preferably, the clamping parts of the two sets of clamping assemblies are distributed in an alternating manner facing each other.

[0069] Optionally, one set of wire clamp components is used to clamp onto the hanging rod 3 under force; the button of another set of wire clamp components has multiple magnets 408 built in, and the magnets 408 are used to attract the wire clamp components to the grounding wire loading and unloading position before loading based on the force clamping of the wire clamp components in the grounding wire loading and unloading position.

[0070] In this embodiment of the invention, the two sets of clamp components can be divided into two operating mechanisms. One set of clamp components is used to clamp onto the hanging rod 3 under force, so that the multi-rotor drone 1 can load or unload the clamp module 4 and the grounding wire 5. The other set of clamp components is used to clamp onto the grounding wire loading / unloading position under force, so that the clamp module 4 and the grounding wire 5 are fixed to the power line. Multiple magnets 408 are built into the button of the other set of clamp components. When the multi-rotor drone 1, carrying the clamp module 4 with the grounding wire 5, gradually approaches the power line corresponding to the grounding wire loading / unloading position, the magnets 408 will attract the clamp component to the grounding wire loading / unloading position.

[0071] In this embodiment of the invention, a grounding wire 5 is welded onto the clamp module 4. The positioning auxiliary module 2 is used to collect flight image information and obtain the grounding wire loading / unloading position, which is then transmitted to the remote control module. The multi-rotor UAV 1 responds to the loading / unloading signal and, based on the flight image information, clamps the clamp module 4 onto the hanging pole 3 by force, thereby loading or unloading the grounding wire 5 at the grounding wire loading / unloading position. The entire grounding wire loading / unloading process is completed by the multi-rotor UAV 1 carrying the clamp module 4 with the grounding wire 5. The clamp module 4 adopts a purely mechanical structure without electrical components, avoiding the potential for damage to electrical components due to accidental power supply. This improves operational efficiency and enhances operational safety, thereby improving the reliability of grounding wire loading / unloading.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
